Desktop Mounting

If the voice gateway is placed on a desktop, do not stack other equipment or paper on the chassis. Provide

plenty of space for air circulation at all four sides of the gateway. Inadequate ventilation can result in

overheating and damage.

Allow space at the back of the chassis for cable connections. Also consider the need to access the chassis

for future upgrades, maintenance, and troubleshooting.

Do not work on the system or connect or disconnect cables during periods of lightning activity.
